Which statement would be used in an argument against the use of human embryonic stem cells for therapy? A. Obtaining embryonic stem cells for use in therapy requires the destruction of embryos. B. Embryonic stem cells are limited in their ability to become different types of cells. C. It is difficult to grow embryonic stem cells in laboratory cultures, so they are not a practical choice for stem cell therapy. D. Embryonic stem cells originate in plants, so the likelihood of rejection by a patient's body is high.

Neelaredoxin is a 15-kda protein that is a gene product common in anaerobic prokaryotes. it has superoxide-scavenging activity, and it is constitutively expressed. in addition, its expression is not further induced during its exposure to o2 or h2o2 (silva, g., et al. 2001. j. bacteriol. 183: 4413–4420). which of the following statements best describes neelaredoxin synthesis? a-neelaredoxin is produced at all times; levels are constant even when exposed to o2 or h2o2.b-neelaredoxin is produced at all times; exposure to o2 or h2o2 increases expression. c-neelaredoxin is produced at all times; exposure to o2 or h2o2 decreases or prevents expression. d-neelaredoxin is only produced when there is exposure to o2 or h2o2.
